Depressive disorder was associated with dysfunctional self-regulation. The current study attempted to design and test a comprehensive self-control training (CSCT) program with an overall emphasis on behaviral activation in depressed Chinese college students.
Participants included 74 students who had diagnosed with major depression, they were randomly assigned to one of the two groups: intervention group (n=37), and control group (n=37). The intervention participants received an eight-week CSCT and four-month follow-up consolidation program, as compared to the control group who received only pre-post-and-follow-up measurements. All participants measured Beck Depression Inventory (BDI-Ⅱ) and Self-control Scale (SCS) at three time points: baseline, post-training, and four-month follow-up.
The dropout rates were 6 (8.1%) in the intervention group and 3 (4.1%) in the control group at the end of six-month intervention. The general linear model repeated measures analysis of variance revealed that comparing with the control group, the intervention group participants had more increase in their trait self-control score, at the meantime, their depressive symptoms had significantly improved. Univariate and logistic regression analyses revealed that participants with milder baseline depressive symptoms were more likely to benefit from CSCT interventions; depression improvement was also associated with the number of sessions attended.
The main limitation was related to the small sample size which consisted of college students who were relatively young and well educated.
The current study demonstrates that CSCT program could temporarily enhance self-control capacity as well as improve depressive symptoms; participants who are mildly to moderately depressed, and who could adhere to the training protocol are more likely to benefit from the intervention.
抑郁障碍与自我调节功能障碍有关。本研究试图设计和测试一种综合自我控制训练（CSCT）方案，该方案总体上侧重于行为激活，以治疗中国大学生的抑郁障碍。
参与者包括 74 名被诊断患有重度抑郁症的学生，他们被随机分配到两组之一：干预组（n=37）和对照组（n=37）。干预组参与者接受了为期八周的 CSCT 和为期四个月的随访巩固方案，而对照组仅接受了预测后和随访测量。所有参与者在三个时间点测量贝克抑郁量表（BDI-Ⅱ）和自我控制量表（SCS）：基线、训练后和四个月随访。
在六个月的干预结束时，干预组有 6 名（8.1%）和对照组有 3 名（4.1%）辍学。一般线性模型重复测量方差分析显示，与对照组相比，干预组参与者的特质自我控制评分增加更多，同时，他们的抑郁症状明显改善。单变量和逻辑回归分析显示，基线抑郁症状较轻的参与者更有可能从 CSCT 干预中受益；抑郁改善与参加的课程次数有关。
主要的局限性与样本量小有关，样本由相对年轻和受过良好教育的大学生组成。
本研究表明，CSCT 方案可以暂时增强自我控制能力，并改善抑郁症状；轻度至中度抑郁且能够坚持训练方案的参与者更有可能从干预中受益。
